Product Description:

The MAC041B-0-BS-4-E/050-A-0/WI656LV/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts low-voltage command currents into precise shaft motion for small indexing tables, pick-and-place heads, and packaging axes. Its compact electromagnetic geometry and integrated position feedback allow the motor to deliver a fast response within the tight machine envelopes common in automated production lines. During operation, its low rotor inertia supports rapid reversals without excessive overshoot, making the unit suitable for light-duty applications that require repeatable point-to-point movements.

The motor has a frame length of B and a 58 mm square flange, balancing torque output with limited mass. Its motor size of 041 indicates a short active core that supports quick acceleration while keeping peak current demand moderate. Heat produced by winding losses leaves the housing through natural convection, eliminating the need for external blowers or liquid cooling circuits. The motor has no blocking brake, so vertical axes must rely on drive holding torque or mechanical locks during a loss of power. Power and protective earth conductors enter through a connector on side A, which directs cabling toward machine backbones and reduces stress caused by tight bend radii. This cable orientation can also help keep the connection away from nearby moving parts when the motor is installed in a compact assembly.

Signal acquisition is handled through an optional tacho feedback module for an incremental or absolute encoder. The standard configuration carries an incremental encoder with standard mounting for velocity and position control loops. This feedback arrangement supports its use as a motor for analog drives, in which analog command voltages regulate current amplifiers instead of relying on digital fieldbuses. The encoder allows the connected drive to monitor shaft movement and correct deviations as the load changes during a motion cycle. Passive cooling also allows the motor to operate without fan noise or additional cooling connections, provided that adequate airflow is available around the housing. Its compact size, feedback arrangement, and brake-free design suit conveyors, light actuators, tool changers, and other applications that use an external method to secure stationary loads.
